PRESS-OPERATING MEANS.

Application filed April 28,

" presently appear.

Another object of the invention is the provision of meansfor supporting certain rotative elements of the structure wherein rigidity and strength are paramount featpres.

Still another object of the invention is to provide flexible elements directly connected to cerain foot-operated means whereby slippage and lost motion may be reduced to a minimum. I I

With these general objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In said drawings:

Figure 1 is a side elevation of a-press embodying my improved operating means.

Fig. 2 is a front elevationthereof, the parts being in the same relative posltions as noted in said Fig. 1.

Fig. 3 is a plan view of Fig. 1,. certain parts of the press being excluded for the sake of clearness.

Fig. 4 is an enlarged elevation illustrating the upper portion of the standard and the means for attaching certain rotativc parts thereto; and, o

Fig. 5 is a detail view of the standard.

Referring now more in particular to the accompanying drawings, wherein like characters of reference denote similar parts throughout the several views, let 5 denote generally a well-known type of press, which embraces the lateral arms 6 and 7 uniting at the top of the press to form the bearing portion 8 adapted to threadedly engage the screw 9, carrying at its lower end the squared member 10 and the usual hand- 1927.

wheel 11 at its top portion. Said press is also provided with a base 12 for attachment to suitable supporting 11102111813, a table for instance. The above structure is siinilarto that disclosed in my co-pcnding applications which also includes a guide 14, (see Fig. 2).

As clearly shown in Figs. 1 and- 2, a spindle 15 is provided with laterally di- .rectcd foot portions 16 for attachment to said wheel 11 and through the intermediary of certain mechanism, about to be described, I propose to rotate said spindle to cause the descent of said screw 9 and its squared member 10 for the obvious purpose of contacting certain dies, (not shown), to effect the production of the artificial flowers. Said mechanism is dual in nature, that is, one portion operates said spindle in one rotatabl direction and during this performance places in operation the other portion of the mechanism for reversing the rotation of said spindle and eventually returningsaid squared member 10 to its elevated position shown in Fig. 2.

Said mechanism comprises member of the pairs being connected to said spindle 15 and certain foot-operating means respectively. Rising vertically from the rear portion of said table 13 is a standard 17, having its inner edge notched, as indicated at 18, Fig. 5, for engagement with the top of said table. At this point said standard is secured to the table, as indicated at 19, and in addition thereto oblique braces20 are provided to secure a stable anchorage for said standard 17. As clearly shown in Fig. 5, bosses 21 and 22 project laterally from both sides of saidstand ard, each being suitably apertured for the reception of shafts 23 and 24 carrying pulleys 25 and 26 andalso sprocket wheels 27 anchored as indicated at 30. To said sprocket wl1eel27 is attached a chain 31 which rotatable members. preferably arranged in pairs, each drops to the base of the press where it engages and is secured to another sprocket wheel 32, mounted on shaft 33 suitably journaled at both ends to the table, as indicated at 3%. Arranged adjacent to said wheel is av somewhat smaller sprocket wheel 35, that latter being connected to another chain 36 extending to a rod 37 operatively carried by a foot treadle 38 journaled on shaft 89 and suitably supported to said table.

From the foregoing it is apparent that down 'ard pressure on said treadle 38 will exert a pull on said chain 36 causing said wheels 32 and 35 to rotate, said chain 31, winding upon said wheel 32 and rotating in unison said sprocket wheel 27 and 25, causing said flexible member 29 to be wrapped around the periphery of pulley 25 and rotating said spindle. l5 and through the intermediary of the screw 9 said squared member 10 descends for contact with certain dies, as aforesaid.

During the functioning of this particular portion of the mechanism, a similar arrangementis being placed in a position to reversely rotate said spindle, as will be pointed out hereinafter.

Obviously the rotation of said spindle by the unwinding of the flexible member 29 causes a second flexible member 40, attached to said spindle, as indicated at 41, to wind upon the latter and this operation rotates said pulley 26 and sprocket wheel 28 causing the chain 42 to exert a rotative pull on another sprocket wheel 48, (see Fig. 2), also mounted on said shaft. 33, thus revolving its companion smaller sprockct wheel it and through the intermediary of a second chain, attached thereto and the rod 5, a second toot treadle 46 rises to a position previously occupied by sald foot trcadle 38. It is manifest that a downward pressure on said treadle a6 in the position just described, will reverse the rotatlve direction of said spindle 15 and elevate said squared member 10 to the position shown in Fig. 2. This operation or operations are continued in alternatiy e form. It will further be noted that throughout the structure the sprocket wheels are each reduced to a diameter somewhat smaller than their companion pulleys, thus providing for a greater amount of flexible member to wind and unwind upon the spindle 15 in view of the increase in travel of the peripheries of said pulleys.

\Vhile the present is a disclosure of the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, as various changes in the minor details of construction, proportion and arrangement of parts may be resorted to without departing from the spirit of the invention as defined in the appended claims.

I claim:

1. In a press, the combination with a rotatable rcciprocatory spindle, a standard, rotatable elements carried by said standard. a flexible member connecting said spindle to one of said rotatable elements. a chain attached to the other of said elements and a treadle operatively connected to said chain and adapted to rotate said elements in unison.

2. In a press, the combination with a rotatable reeiprocatory spindle, a stamlard, rotatable elements mounted in pairs on both sides of said standard, flexible members oppositely wound on said spindle and having their opposite ends secured to one element of each pair, chains connected to each of the other elements of the pairs and treadles operatively connected to said chains and adapted to alternately rotate said elements.

3. In a press, the combination with a rotatable reciprocatory spindle, a standard presenting a pair of apertured bosses, rotatable elements mounted in pairs in said apertured bosses, each pair being adapted to be rotated in unison, flexible members connected to one rotatable element of each pair and having their other ends oppositely wound on said spindle, chains connected to each of. the other rotatable elements of each pair and foot treadles operatively connected to the other end of each of said chains and adapted to be manipulated to dispose thornselves in alternative operable iorin.

4-. In a press, the combination with a rotatable reciprocatory spindle, a standard, rotatable elements mounted in pairs on both sides of said standard and comprising a paired pulley and sprocket wheel somewhat smaller than said pulley, flexible members oppositely wound on said spindle and having their opposite ends secured to said pulleys, chains connected to each of said sprocket wheels and treadles operativcly connected to said chains and adapted to alternately rotate said elements, the rotative movement of said chains being less than the rotative movement of said flexible members attached to said pulleys.

In testimony whereof I allix my signature.

FRANK BLANDO.
